Flash Furniture Kelista Mid-Back Chair

Having approved the purchase and repair of thousands of office chairs during my property career, I've seen very high and low end task seating. In my opinion this falls about low middle in quality. There is a reason corporations spend much more for task seating: durability/safety/worker comfort (read: avoid injury claims).After using for two months, my observations:Pro: looks good, comfortable seat/back/arms. Breathable back fabric. My 5 ft high female partner loves the ability to adjust height more than fixed seating - allowing her to work comfortably at the kitchen height table on a laptop, feet resting on the base, thereby achieving a reasonably ergonomic seating posture. 8 weeks in, with the exception of the tilt the chair performs as advertized- with one exception (see below). Assembly was straightforward, although awkward for one person, but achievable by inverting the chair being assembled and placing it on a surface that will support the seat without (sofa arm in my case), while attaching the back and arms.Cons:The tilt feature (of which I am a big fan) is worthless. The adjusting knob changes nothing rendering the back essentially fixed in place. The back fabric (netting) was pierced by a pen in the back pocket - so far the puncture has not resulted in a tear.My opinion:A decent and affordable task chair for an hour or two of daily use.The piston (height adjustment) is not of typical commercial quality, and would look elsewhere if it were regularly adjusted for more than one person.While other have appreciated the lightness of the chair, I prefer a much heavier base to add stability, particularly for chairs being rolled while in use. We are not large people (less than 165lbs).Were I looking for a task chair for long hours of daily use (without spending $500+), I would look for a supplier selling used office furniture, where Steelcase/Herman Miller/Hon etc. can be bought for a fraction of new pricing.
